HYDRAULIC PRESS.

Specification of Letters Patent.

Patented July 25, 1911.

Application filed September 16, 1910. Serial No. 582,298.

To all whom 'it may concern:

Be it known that we, JOHN BECKER, a citizen of the United States, and aresident of National City, in the county of San Diego and State ofCalifornia, and ADOLPH BEYER, a citizen of the United States, and aresident of San Diego, in the county of San Diego and State ofCalifornia, have invented certain new and useful Improvements inHydraulic Presses, of which the following is a specification.

Our invention relates to hydraulic presses in which the pressure isproduced by means of a liquid forced into a cylinder by a pump and isreleased by means of other pressure, and it is to be used moreparticularly for pressing and separating the juice from the pulp offruits of various kinds, and the objects are: First-To provide a simple,efficient, economically constructed and easily operated press. Second.Toprovide a. press that is easily accessible for filling and emptying andfor keeping it in a sanitary condition.

Vith these and other objects in view, our invention consists of certainnovel features of construction, combination and arrangement of parts, aswill appear in the detail description and is particularly set forth inthe appended claims, reference being had to the accompanying drawings inwhich Figure 1 is a side elevational view of the press, Fig. 2 is alongitudinal sectional view' thereof, Fig. 3 is a top view thereof, Fig.4: is a sectional view taken through A. B. in Fig. 2, and Fig. 5 is asectional view taken through C. D. in Fig. 2.

Similar characters of reference refer to similar parts throughout theseveral views.

The hydraulic cylinder 1, press cylinder 2, hydraulic piston 3, pistonrod 4, press piston 5, press cylinder extension 6, bottom 7, relief gate8, tie rods 9, braces 10, base 11,

' and valves 12 and 13, form the principal parts of our machine. Thehydraulic cylinder 1 is provided on its upper end with cylinder head 1substantially attached thereto by means of bolts 1", and centrallylocated therein is provided a hole 1 adapted for a feed pipe 12 to bescrewed therein.

On the lower end of cylinder 1 is provided another cylinder head lsubstantially attached to the lower end by means of bolts 1 Centrallylocated in said cylinder head 1 is provided a hole in which operatespiston rod 4:, and around said piston rod 4 in the outer surface ofcylinder head 1 is provided a stuffing box 1 for the purpose of forminga tight joint around piston rod 4:. The upper end of piston rod 4 isreduced in size and tapered at 4* and adapted to fit a hole in hydraulicpiston 3, and on its extreme upper end is provided a nut e which screwson piston rod 4 against piston 3 on said piston rod. Said piston 3 isprovided with a leather cup 3 which is firmly held in place by 'means ofan annular retaining washer 3 and tap bolts 3 Said piston 3 is adaptedto fit and operate in cylinder 1. In the lower end of cylinder 1 and inthe one side thereof is provided another feed pipe 13 Adjacent to saidcylinder 1 and directly beneath it is provided a pressure cylinder 2 inwhich operates piston 5 which is substantially attached to the lower endof piston rod 4, and is adapted to fit said cylinder 2, and operatetherein. The upper end of cylinder 2 is provided with an extension 6which is substantially attached thereto, and on the one side of saidextension 6 there is provided a hinged door 6 hinged at point 6*. Thisdoor is for the purpose of facilitating the filling of the presscylinder. Said cylinder 2 is provided on its lower extended end withbottom 7 which is provided with an annular projection 7 adapted to fitinto an annular groove in the lower end of cylinder 2. The upper surfaceof bottom 7 is concave and has mounted thereon a plurality of screens ofdifferent sized meshes 7*. Just beneath said bottom 7 and rigidlyattached thereto by means of bolts 8 is provided support 8 whichsupports said bottom 7 and with it acts as a door for the exit of thepulp after it has been sulficientlypres'sed. This support 8 is shaped asshown best in Fig. 5, and it is supported by means of nuts 9 On oppositesides of said press are hinged pieces 8 and 8 adapted to support theextended edges of bottom 7 These hinged pieces 8 and 8* are adapted tobe swung out-ward allowing the parts 7 and 8 to descend until theannular projection 7 is below the lower surface of cylinder 2, whenparts 7 and 8 may be swung to one side on one of the tie-bolts 9, thusallowing the ready exit of the pulp. The machine is supported on theextended ends of tie-rods 9, which are substantially braced by means ofbraces 10. Said tie-rods 9 and braces 10 are substantially attached tochannel iron base 11, by means of bolts 10 and nuts 10. The cylinders 1and 2 are substantially held in their relative positions by means of tierods 9 which are provided on each of their ends with nuts 9 and 9*. Onthe upper end of cylinder 1 and across the head 1 is provided a link 14through which the upper extended end of bolts 9 protrude. This link 14acts as a bar across the head of the machine, and reinforces thecylinder head 1 and holds the tie-bolts 9 in their relative positions.Each of the cylinders are substantially ribbed for strength and areprovided with guide pieces 2 and 1 through which rods 9 extend. Inconnection with feed pipe 12 is valve 12 which connects with a hydraulicpump by means of pipe 12 and also with a drainage pipe 12.

In connection with pipe 13 is another valve 13 which is in connectionwith a service pipe 13 and drainage pipe 13. These valves 12 and 13 areconnected by means of a rod 12 and are arranged so thatwhen one is openfor feed the other is closed against feed and open for drainage, andvice versa.

Although we have drawn and described a particular construction, we donot wish to be limited thereto, but we desire to include in ourinvention substantially the principles embodied together with the parts.

It will be readily seen that by this construction, we have provided avery efficient, economically constructed and easily operated hydraulicpress, that the feed and discharge are very simple and easily operated.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is 1. In a hydraulic press the combination of ahydraulic cylinder provided with cylinder heads, a stuffing box in oneof said cylinder heads, a combined inlet and outlet pipe centrallylocated in the other cylinder head, a piston in said cylinder, a twosection press cylinder provided with an annular groove in its lower end,a piston therein in connection with the aforementioned piston, anedgewise swinging door provided with an annular projection adapted tofit into said annular groove mounted on a vertical axis in connectionwith said press cylinder, a sidewise swinging door in the side of saidpress cylinder, a plurality of screens on the inner surface of thebottom of said press cylinder, tie bolts connecting said cylinders, andmeans for regulating the hydraulic operation of said press, allsubstantially as set forth.
